The New York Times: Restrictive Covenants Stubbornly Stay on the Books
Matoko Rich weighs in again with a solid piece on race restrictive covenants that remain in CC&Rs despite being unenforceable and contrary to public policy. Includes a quote from your humble servant, to wit:

Evan McKenzie, a professor of political science at the University of Illinois at Chicago who has written about restrictive covenants in homeowner associations, said: "While the covenants are there, there is still room for people to think that although it cannot be legally enforced it is nonetheless a promise that they are morally obligated to keep. And that's an argument in my view for removing them."
